摘要： A process for purifying an ethanol stream that comprises byproduct, such as aldehyde, acetals, and/or esters, but withdrawing a sidestream comprising ethanol from a distillation column. The sidestream may have a reduced concentration of aldehyde that reduces the formation of acetals in subsequent purification of the ethanol stream.
摘要翻译： 一种纯化乙醇流的方法，其包括副产物，例如醛，缩醛和/或酯，但是从蒸馏塔中取出包含乙醇的侧流。 侧流可能具有降低的醛浓度，从而在乙醇流的随后纯化中减少缩醛的形成。

摘要： Recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid and by reacting a portion of the crude ethanol product or one or more derivative streams containing ethyl acetate obtained therefrom in the presence of hydrogen, via hydrogenolysis. The one or more derivative streams comprise ethyl acetate that are reacted via hydrogenolysis to form additional ethanol that may be directly or indirectly fed to the separation zone or the hydrogenation reactor.

摘要： Recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid using a low energy process. The crude ethanol product is separated in a column to produce a distillate stream comprising acetaldehyde and a residue stream comprising ethanol, acetic acid, ethyl acetate and water. The ethanol product is recovered from the residue stream.
